Quantification of IL-17RC and IL-17RA mRNA in MF and benign skin biopsies. Skin biopsies from individuals with MF, chronic dermatitis (CD), psoriasis (PSO), and normal healthy skin (NS) were analyzed by QPCR using primers specific to IL-17RC, IL-17RA, and GAPDH mRNA. The expression of IL-17RC and IL-17RA was normalized to GAPDH, so that the levels shown represent copies of (A) IL-17RC or (B) IL-17RA mRNA per 1000 copies of GAPDH mRNA. Bars denote the average and standard deviation for each skin type analyzed.
